SlrECIFICATION forming part of Letters Patent No. 700,854, dated May 27, 1902.

Application filed May 23,1901.

To all w/tom it puny concern:v

Be it known that I, JOEL STRAHM, a citizen of the United States, residing at Bern, in the county of Nemahaand State of Kansas, have invented certain new and useful Improvements in Tank-Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to a heater for water troughs and tanks and for cooking'feed for stock, the purpose being the provision of a simple device of this character which can be operated economically and which is of great heating capacity, so as to warm a given amount of water or cook any required quantity of feed in a comparatively short interval of time.

With these objects in view and such others as may result from the specific structural organization of the heater the invention consists of the novel features, details of construction, and combinations of the parts which hereinafter will be more particularly set forth and finally claimed.

In the drawings, forming a part of the application, Figure 1 is a vertical central section of a heater embodying the invention and showing it applied to a trough or tank. Fig. 2 is a perspective view of the heater. Fig. 3 is a perspective view of the ring removably fitted within the body to concentrate the fuel and form the annular combustion and smoke chamber.

Corresponding and like parts are referred to in the following description and indicatedin all the views of the drawings by the same reference characters.

In its construction the heater comprises a vertical body 1, a base portion 2, and an outlet-pipe 3, the latter serving to carry off the products of combustion and to insure a circulation of air through the fuel, which is essential to promote combustion thereof. The

body 1 and base portion 2 are formed so to to prevent the entrance thereinto of water or other liquid, and the bodyl reaches to aheight so as to extend above the level of the water or feed in the trough or tank 4, so as to prevent entrance of the same by splashing or The body 1 may otherwise into the heater.

and gases rise and circulate.

be of any cross-sectional area and outline is constructed to provide an annular chamber 5 into and through which the hot air, smoke, The outletpipe 3 communicates with the annular chamher 5, so as to carry off the hot air and products of combustion. The annular chamber 5 may be formed in any convenient way, and in order that its depth may be regulated it is preferred to provide a ring 6, which is removably fitted within the body 1 and is supported therein by an outer flange a. at the upper end of the ring engaging with an inner flange 79 at the lower end of the body 1. This ringprojects below the top of the base portion 2 and forms the inner wall of the annular chamber 5. This ring can be removed when burned or otherwise disabled forfurther effective service and can be replaced by a new one. The removability of the ring 6 enables it to be substituted by a ring of greater or less height, according to the required depth of the chamber 5. By having the base portion of greater diameter than the body 1 and made shallow the heat is radiated more quickly to the liquid or feed in which the device may be immersed.

The heater maybe constructed solely of sheet metal or may be cast or may be partly formed of cast metal and sheet iron or steel,

as found most advantageous, according to the size and special use for which the device is designed.

When placed in the trough or tank 4, the heater is secured in place by rods 8, which may be passed through openings in lugs or ofistanding portions 9, applied to the base portion 2 or other laterally-projecting parts 10 of the body portion 1. The manner of securing the heater in the trough is immaterial within the scope of'the invention and is a matter of minorimportance. The outlet-pipe 3 is connected by a brace-piece 11 with the upper end of the body 1, and the latter is closed by a cap 12, having a damper 13, by

means of which the draft can'be controlled, according as a brisk or slow fire is desired to be maintained in the heater. The central portion of the base 2 constitutes the fuelchamber and the outer portion the combustion-chamber, which has direct communication with the annular or smoke chamber 5. After the fire has been started the draft is controlled by means of the damper 13, and the smoke and gases rise into the chamber 5 and pass off through the pipe 3. Fuel is supplied through the body 1, and the ashes are removed through the said body by means of a shovel, scoop, or like contrivance.

The top 15 of the hollow base 2 has an opening to receive the lower end of the body 1, and a rim 14 surrounds the said opening and encircles the lower end of the body 1, to which it is riveted, bolted, or otherwise firmly attached.

Having thus described the invention, what is claimed as new is end of the hollow body and hold the ring sus pended Within the upper portion of the hollow base, an outlet-pipe connected to the top of the base at one side of the hollow body, and a cover fitted to the upper end of the hollow body and having damper-controlled openings, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
